On this site you will find
the results of my first steps in Digital Astronomy. For many years I did Deep-sky photography, but recently I made my first steps in the digital world. My pictures using film photography are
found at my homepage
For digital imaging I initially used a Celestron C5 (aperture 5 inches) f/10 and a 32 cm f/4.7 Newton telescope. Most results currently presented are produced with the C5,
because this is a very useful instrument for a beginner in WebCam imaging.To extend the focal lengths of the instruments a Meade 2x Barlow lens was used.
As a recording instrument I use a Philips ToUcam Pro camera. Currently I use a Celestron C11 Schmidt-Cassegrain telescope with a focal length of 2800 mm.
Most of the time I take about 100-200 exposures of 1/25 sec and combine the pictures using the
AstroStack program of R.J.Stekelenburg
